Which algorithms map best to GPUs and other vector-processors? What kind of algorithms are faster when using accelerators and OpenCL? StreamComputing investigates new problem spaces based on a starting point from “The 13 (computational) dwarfs of OpenCL” document by Professor Wu Feng and his group from VirginiaTech.
Altera announced that its SDK for OpenCL is conformant to the OpenCL 1.0 standard and is now included on the Khronos Group list of OpenCL conformant products. Altera is the only company to offer an FPGA-optimized OpenCL solution, allowing software developers to harness the massively parallel architecture of an FPGA for system acceleration. Altera will demonstrate its OpenCL solutions at the 2013 Linley Processor Conference, being held October 16-17 in Santa Clara, Calif.
PCMark 8 now includes support for Windows 8.1 and some cleaned up OpenCL options.
AnandTech takes a look at Altera's OpenCL SDK for their FPGA. Altera introduced a private beta for OpenCL on FPGAs late last year and the SDK has now been made public. Altera's implementation is built on top of OpenCL 1.0 but offers custom extensions to tap into the unique features of FPGAs.

Intel has announced that Release 2 (R2) of the Intel SDK for OpenCL Applications 2013 XE now adds Beta support for Microsoft Windows Operating Systems on Intel Xeon Phi coprocessors. The SDK continues to support Red Hat Linux and SUSE Linux. Available as a free download, the XE version provides a comprehensive development application environment that supports the full OpenCL 1.2 standard on platforms with Intel Xeon processors and Intel Xeon Phi coprocessors. The XE Version targets at developers of highly parallel applications including High Performance Compute (HPC), workstations, and data analytics. In addition, Intel provides an SDK designed for developers of visual computing applications. The Intel SDK for OpenCL Applications 2013 supports the Intel Iris Graphics and Intel HD Graphics family on 3rd and 4th Generation Intel Core Processors using Windows 7 and Windows 8 operating systems. Download the Intel SDK for OpenCL Applications 2013 XE Release 2.
At at IBC this year, AMD demonstrated a 4K CinemaDNG workflow for Blackmagic Design DaVinci Resolve 10 color-grading. Using a Supermicro 7047GR-TRF SuperWorkstation to run four AMD FirePro W-series graphics cards, the GPU-accelerated workflow relied on Blackmagic's OpenCL support for Windows and Mac to enable real-time playback of CinemaDNG.
At the International Broadcast Conference, Vanguard Video announced H.265/HEVC codecs for a broad range of hardware and software platforms, including x86, ARM, OpenCL GPU, and FPGA IP Cores. Vanguard Video is previewing an OpenCL GPU HEVC encoder accelerator that more than doubles the performance of the V.265 software encoder running on the main processor. This technology was demonstrated at the Intel booth.
Imagination Technologies has developed a set of extensions to allow image conversion on the fly, using the Khronos Groups OpenCL and EGL technology. ImgTec converts the camera YUV data to RGB using the OES_EGL_image_external extension, and then use PowerVR’s zero-copy functionality to directly access the camera texture data from OpenCL. Find the in-depth explanation on ImgTec's website.
AMD announced that its collaboration with Adobe has reached a new milestone for more sophisticated professional video workflows. Using OpenCL acceleration means that video and film professionals, as well as enthusiasts, can take full advantage of the massively parallel compute power of AMD APUs, Radeon graphics, and AMD FirePro professional graphics when working with Adobe Premiere Pro CC, Adobe SpeedGrade CC, and Adobe Media Encoder CC by exploiting AMD App Acceleration.
